Specification of Letters Patent.

Patented July 2, 1912..

Original application filed April 14, 1910, Serial No. 555,354. Divided and this application filed June 5,

To all whom it'maj concern.

Be it known that I, JOHN E. CONZELMAN, a, citizen of the United States,residing at the city of St. Louis, State of Missourhhave invented certain new and useful Improvemer ts in Concrete Construction, (Divisional Case ll.) of which the following is a spec1-. q ie J This application is a division and continuation of one filed by me April 14, 1910,- Serial No. 555,354.

This invention relates to certain new and useful improvements in concrete construc tion in which concrete beams are used to support.concrete' slabs and are themselves supported by means of columns or uprights The objectto'f the invention is to provide improved andefl'ective means for uniting a superposed column to a supporting column,

and at the same time to connect the beams and slabs supported by 'the latter to both columns so' that the completed structure will be as. an integral mass.

In the drawings: Figure 1 is a top plan view of the invention, the superposed column being omitted. Fig; 2 is a-section taken on the line 2&2 'of- Fig. 1, the superposed column being shown in position. Fig. is a section-taken on the line of Fig. 1, and Fig. 4 is a perspective view on an enlarged scale of one of the connecting, members.

In accordance with the present invention, a lower concrete column 7 is provided with a cap 6, molded integral therewith, a plate 50 being set in the top face of cap 6. The uppercoluinn designated 19 has a similar plate 51'set in its bottom end, the columns being arranged in spaced relation, the upper column 19 being supported by means of the connecting members or posts 52. Vertical bars are en'ibcdded in column 7, and extend through perforations in plate and, also, through perforations in'the lower ends of the posts The bars 25 are threaded at. their free ends, and. receive'nuts 53, which act to not only secure plate 50 to column 7 but, also, bind the posts firmly to said plate. The upper ends of members 52 are 57, as clearly depicted in Fig.2.

Serial No. 631,281.-

isimilarly secured to plate 51 by means ofnuts 54 on the threaded lower ends of bars 46, the bars being embedded in column 19 and have their threaded ends extending through perforations inplate 51 and also,

through perforations in the upper ends :of-

posts 52.

The endsof each beam 55 rest upon cap 6 of'lower column 7, and are oppositely: disposed in pairs, so thatvthe posts 52 are located between the beam ends, the beams being preferably of the same shape in crossscctional configuration as the beams disclosed in my co pending application filed Nov. 16, 1909, Serial No. 528,298..

Each side of each of the beams 55 is provided with a shoulder 56, and a tenon 57 located between the shoulders, a portion of the end of each tenon adjacent the columns being cutaway as indicated at 58. A flange; 20 is provided at. the sides andends of slabs- 3, the flanges being cutaway as indicated at 70 to form spaces in which the shoulders 56 of beams 55 are received, the top surfaces of the slabs being located above the teno'ns, A space 59' is thus formed between the two slabs 3 supported by a beam. The cornersof each'slab 3 are located above cap 6 and are provided with cut-away portions (30, Which unite to form space 61 through which members 52- lower part of beam 55, and preferably pr oject from the ends of same into space 61, in order to lap or shut similar-"bars 62 that pro-- ject from an oppositely-disposed beam 55, some of said bars 62 being bent upwardly to project from the ends of tenon 57. Other reinforcing. bars 63, which are embedded in tenon 57, project from same into space 61 and have their ends located opposite similar bars 63 that project from a tenon 57 of an oppositely-disposed beam 55. Bars 6 1 are embedded in shoulders 56 and are connected at intervals by the inverted'U-shaped bars 65. U-shaped bars 66 are embedded at inunderlie bars 62. A so-called form (not shown in the drawings) is laced around the base of column 19, and sai form-and spaces 59 and 61 are filled with grout or plastic concrete. The grout or plastic concrete sets in said form and spaces 59 and 61, being supported while plastic in said spaces by means oftenon'57 and cap 6 and the boards or formers, which close the sides of space 61,

and unites slabs 3, beams 55, and columns 7 and 19 integrall together. The grout or concrete in the. orm encircling'the base of column 19 forms a concrete ring 67 that is integral with column 19 and covers the upper end of each member 52. As additional strengthening means, a ring of expanded metal 68 or the like is embedded in ring 67 and is preferably arranged to encircle the base of column 19 and, also, to extend into the grout or concrete in space 61.

Bars 43 are embedded in column 7 and in cap 6 and are bent to surround bars 25 in column 7, one bar 43 in cap 6 being located adjacent bars 25, and the other bar 43 being arranged near the perimeter of said cap. A bar 47 at the base of column 19 encircles the bars 46 in said column.

What is claimed is:

1. A concrete structure including a supporting column, reinforcing bars projecting from its top, members resting on said column and being secured to said bars, a superposed column resting on said members, reinforcing bars projecting from said superposed column and being secured to said members, beams resting on said supporting column, slabs resting on said beams and having cut-away portions, said cut-away portions uniting to form a space around said members, and a concrete filler for said space adapted to set integrally with said columns, said beams, and the edges of said slabs surrounding said space.

2.

3. A concrete structure including a supporting column, a plate surmount-ing the same, reinforcing bars projecting from said column, members resting on said plate and being secured to said bars, a superposed column, a plate underlying said superposed column and resting on sald members, reinforcing bars projecting from said superposed column and being secured to said members, beams'resting on said supporting column, slabs having cut-away portions uniting to form a space around said members, a concrete filler for said space adapted to set integrally with said beams, said column, and the edges of said slabs surrounding said space, and a concrete ring formed around the base of said superposed column.
